Automatically discover tools for Azure OpenAI Realtime API

Azure now provides a unified Realtime API for low‑latency, multimodal conversations over WebRTC or WebSockets. If you’ve used the earlier preview versions (for example the GPT‑4o realtime preview), the new generation model is simply called gpt-realtime and the API follows the same event-driven pattern: you open a session, configure defaults via session.update, stream input, and receive streaming output (text, function calls, audio, etc.).

Azure Document Intelligence – Fix: ContentSourceNotAccessible (Invalid data URL)

Problem

Training custom models (for example, delivery notes) in Azure Document Intelligence initially worked fine. Suddenly, both training and auto-labeling started failing with “Internal Server Error”. In the model details, the following appeared:

Provision Microsoft Fabric with Azure Bicep

Overview

Microsoft Fabric consolidates analytics workloads (including Power BI) on a tenant-wide capacity. These Fabric capacities (SKUs F2–F2048) can be provisioned declaratively with Bicep like any other Azure resource. This post covers:

Automatically deploy GPT-4.1 Mini in Azure OpenAI via Bicep

The official Microsoft documentation on deploying Azure OpenAI models is generally helpful, but specific examples are often still missing, especially for new models such as gpt-4.1-mini and newer SKU types such as DataZoneStandard. Anyone who wants to provide a current model such as the gpt-4.1-mini programmatically is therefore quickly faced with unanswered questions.

Easy handling of optional Azure Web App settings in Bicep

Often you don’t need all the configurations of an app per stage; sometimes they are optional. This is often the case for the development stage in particular.

Efficient deserialization of Json files on Azure Blob Storage with .NET

System.Text.Json is currently the most modern way to handle Json files efficiently. Efficiency here also means that memory sparing files are read in.

Avoid hardcoded Microsoft URLs with Bicep environments

Bicep has a great feature, which meanwhile also leads to warnings during execution if you don’t pay attention to it: the avoidance of static values like URLs in Bicep files. A corresponding warning looks like this:

Create Azure Active Directory App Registration with Azure CLI

There are now an insane number of ways to register applications in Azure Active Directory - but many ways are no longer supported or have been discontinued, for example the old Azure PowerShell tools.

Serve a SPA like Angular or React on Azure App Service for Linux

In many scenarios it can make sense to host single page applications via an Azure Web App, for example if you have many small applications - then the Static Web App will simply be more expensive. Likewise, it can be very convenient to host a Single Page Application on Web Apps if you have the App Service Plan anyway because you run multiple APIs with it.

Validate Bicep config during CI/CD with Azure DevOps

Bicep scripts are ideally part of the source code and can also be used as such in the build process of the application.

What's Bicep on Azure and why you should use it?

To generate resources automatically in Azure, you could either do Azure Resource Manager templates, which no one really wanted to do because they are far too complex and clumsy - or use third-party solutions Terraform and Pulumi.

Loggen eigener Werte mit Azure Application Insights

Um eigene Werte in Application Insights loggen zu können, muss ein eigener ITelemetryInitializer erzeugt werden. Dieser dient nun dazu, dass der entsprechende Log-Kontext um Informationen angereichert werden können:

Loggen des User Agent mit Azure Application Insights

Standardmäßig wird der User-Agent des HTTP-Requests nicht von der Application Insights Middleware des ASP.NET SDKs gespeichert; vermutlich aufgrund der sehr strengen Implementierungsart der DSGVO-Vorgaben von Microsoft.

Azure Active Directory nun auf .NET Core!

Azure Active Directory gehört zu den größten Anwendungen im Azure Ökosystem und vermutlich zu einer der größten Anwendungen der Welt.

Loggen des Referers mit Azure Application Insights

Standardmäßig wird der Referer, also die Quelle des Aurufs des HTTP-Requests, nicht von der Application Insights Middleware des ASP.NET SDKs gespeichert. Um dies dennoch im Log zu hinterlegen, muss ein eigener ITelemetryInitializer geschrieben werden.

Was ist Azure Static Web Apps?

An der Microsoft Build 2020 hat Microsoft seinen neuen Dienst Azure Static Web Apps vorgestellt.

Auch wenn die Bezeichnung Static Web Apps zunächst etwas kurios wirkt, geht es durchaus um dynamische Anwendungen - jedoch vor allem um das statische Ausliefern solcher Web Apps, wie sie zum Beispiel Angular, React oder andere Single Page und Progressive Web Apps darstellen.

Microsoft Build 2020 - Neues für .NET Entwickler

Am heutigen Dienstag um 17 Uhr deutscher Zeit startete die Microsoft Build - dieses Jahr als kostenloser Online-Event statt einem kostenpflichtigen On-Site Event, meist in Downtown Seattle.

Store Messages of Azure IoT Hub to Azure Blob Storage

In most cases, Azure IoT Hub messages should be stored for a longer period of time.

In fact, there are several ways to achieve this goal - and there are huge differences in performance and price.

Device Twins vs Digital Twins in Azure IoT

Device Twin vs. Digital Twin in Azure IoT

Again and again you read about Device Twins, Digital Twins or Device Shadows - but what is that actually, and why do the names sound so similar?

Setup the local Azure IoT Edge development container

Azure IoT Edge as a product is in principle not just a simple application or a simple container, but is actually more of a runtime for an ecosystem on a device.

Azure IoT: send messages with C#

Requirements

• You must have created an IoT Hub in Azure.
• You must have created a device in your created Azure IoT Hub .
• You need the connection string your IoT Hub device (IoT Hub -> Devices -> Select Device -> Configurations)

NuGet

To use the DeviceClient , which opens the connection to your Azure IoT Hub , you need the NuGet package Microsoft.Azure.Devices.Client

Setting up an Azure IoT Hub

The Azure IoT Hub is a highly scalable, secure platform for the bidirectional communication of devices and software components in the sense of IoT - both in the area of industrial IoT (IIoT) and in the simple IoT for devices. In addition to device communication, the Azure IoT Hub can also provide device provisioning.

Upload to Azure Storage with PHP

I had the wonderful task to change a 20 year old PHP software during a Lift-and-Shift migration to Azure, so that it doesn’t store files directly in the web folder anymore, but uploads them to an Azure Blob Storage.

Update Azure Storage Blob Properties with PowerShell

In the past days I uploaded a lot of files to an Azure Blob Storage using the Azure Storage Explorer.

Azure Saturday 2018: Keynote by Donovan Brown

Yesterday we had the Azure Saturday 2018.

Enjoy the Keynote Enterprise transformation (and you can too) by Donovan Brown:

Azure Saturday

Azure Saturday Munich is a free community-focused Azure event dedicated to educating and engaging members of the local technical community. Azure Saturday draws upon the expertise of local Azure IT professionals, developers and solutions architects who come together to share their real world experiences, lessons learned, best practices, and general knowledge with other like-minded individuals.

IoT im Maschinenbau: die Cloud ist nicht genug

Effizient und sicher in der Connected Factory mit Edge Computing

Cloud-Projekte in Unternehmen haben in den aller meisten Fällen eines gemeinsam: die Verbindung des eigenen, bestehenden Rechenzentrums mit der Cloud – die hybride Connectivity; oft umgesetzt mit VPN oder im Falle von Azure über die Express Route.

Microsoft Azure CosmosDB Unique Key Policy

If you want to create custom unique keys inside a collections, you can simply create a UniqueKeyPolicy while creating your collection.

Aktivieren des impliziten OAuth2 Flow in Azure Active Directory

Implicit OAuth2 Flow

Der Implicit OAuth2 Flow ist eine vereinfachte Variante des Browser-Ablaufs für Clients, die zum Beispiel auf JavaScript basieren und direkt im Browser ausgeführt werden. Per default ist dieser in Azure Active Directory deaktiviert.
